Convert 60 to 80 degrees Fahrenheit to degrees Celsius.

1) \( a=8 \frac{2}{5} \) vo \( b=1 \frac{1}{20} \) olduqda \( 0,2 \cdot(a: b) \) ifadosinin qiymotini tapın. 2) \( a=1 \frac{3}{23} \) vo \( b=4 \frac{5}{23} \) olduqda \( (b: a): 2 \frac{1}{2} \) ifadosinin qiymotini tapın.

Умножь: \( \frac{2}{17} \cdot 4=\frac{\square}{\square} \).

a. \( \frac{1}{4} \cdot \frac{3}{4}= \)
